People reports that the pair exchanged vows at San Ysidro Ranch in Montecito, Calif., in front of plenty of celebrity guests, including Chelsea Handler, Rosie O'Donnell, Whitney Cummings and Peter Facinelli.

Etheridge and Wallem, also 53, started dating in 2010. Wallem is a producer on "Nurse Jackie," and previously wrote for "Cybill" and "That '70s Show."

They announced their engagement last summer after the Supreme Court struck down on the Defense of Marriage Act. "I look forward to exercising my American civil liberties," Etheridge tweeted at the time, "and getting fully, completely and legally married this year to my true love of over three years, Linda Wallem."

Etheridge has four children from previous relationships with Tammy Lynn Michaels and Julie Cypher.
